Abstract

Dynamic recrystallization(DRX) behaviors of 18Ni maraging steel during hot deformation have been investigated by single-pass thermo-mechanical simulative experiment at temperatures of 1173K-1323K and strain rates of 0.001s-1-1s-1. The results show that the true stress-true strain curves type of this alloy is DRX. The DRX in 18Ni maraging steel is easy to occur at low strain rates and high deformation temperatures. Using regression analysis, the activation energy(Q) for DRX of 18Ni maraging steel was calculated to be 413544.96J/mol. The constitutive equation of peak stress for DRX was also obtained. The mathematical models of critical stress and critical strain were finally established.
